摘要：

针对新型多层移动传感网络结构下的传输移动控制问题，提出一种三角网格轨迹模型。在三角网格模型下设计F-connect移动策略，给出动态二锚节点定位算法triangle-grid，绘制区域三角网格节点分布图，结合EHCC-communication性质控制F-collect移动以收集S节点的数据信息。模拟实验结果表明，该模型能较好地解决随机移动节点带来的网络不稳定、信息丢失率高等问题，且适用于大规模的无线传感网络，只需布置少量F-collect节点就能获得较高的网络覆盖率和较低的数据丢失率。

Abstract:

In the new tiered mobile network architecture, this paper proposes a triangle-grid orbit movement and transmission control model. Based on the model, it designs a movement policy of F-connect and proposes a dynamic two-anchor nodes localization algorithm to compute area triangle-grid nodes map. By combining the map and EHCC-communication lemma, it controls the F-collect to collect the data of S. From the simulation, it obviously indicates that this project movement control strategy suits extremely the large-scale Wireless Sensor Networks(WSN). When the network scale achieves certain degree, it can show the superior performance in data collection. The proposed model provides a good solution of the problem on tiered mobile network of instable communication and high-fraction of event loss.
